avoid remove&reinsert of call when splitting block for inlining

We used to split the inlined-into block at (= after) the call, and then
remove the call from the first block to insert it in the second.

The removal may cause unnecessary and unrecoverable resetting of debug
insns: we do not generate debug temps for calls.

[AArch64] Tighten move constraints for symbolic operands

The movsi and movdi constraints allowed the source to be any
absolute symbolic expression ("S").  That's OK for operands that
have already been vetted by the aarch64_mov_operand predicate but
causes problems if the register allocator substitutes an equivalence
(the usual "the constraints can't accept more than the predicates"
restriction).

Although all other uses of "S" in the backend are redundant and could
in principle be removed, "S" itself is a publicly-documented constraint
and so we'd have to keep its definition.  This patch therefore adds a
new "Usa" constraint for legitimate absolute address operands.

Record equivalences for spill registers

If we decide to allocate a call-clobbered register R to a value that
is live across a call, LRA will create a new spill register TMPR,
insert:

   TMPR <- R

before the call and

   R <- TMPR

after it.  But if we then failed to allocate a register to TMPR, we would
always spill it to the stack, even if R was known to be equivalent to
a constant or to some existing memory location.  And on AArch64, we'd
always fail to allocate such a register for 128-bit Advanced SIMD modes,
since no registers of those modes are call-preserved.

This patch avoids the problem by copying the equivalence information
from the original pseudo to the spill register.  It means that the
code for the testcase is as good with -O2 as it is with -O,
whereas previously the -O code was better.

diagnostic.c: add print_option_information

This patch simplifies diagnostic_report_diagnostic by moving
option-printing to a new subroutine.

Doing so required a slight rewrite.  In both the old and new
code, context->option_name returns a malloc-ed string.
The old behavior was to then use ACONCAT to manipulate the
format_spec, appending the option metadata.
ACONCAT calcs the buffer size, then uses alloca, and then copies the
data to the on-stack buffer.

Given the alloca, this needs rewriting when moving the printing to
a subroutine.  In the new version, the metadata is simply printed
using pp_* calls (so it's hitting the obstack within the
pretty_printer).

This means we can get rid of the save/restore of format_spec: I don't
believe anything else in the code modifies it.

It also seems inherently simpler; it seems odd to me to be
appending metadata to the formatting string, rather than simply
printing the metadata after the formatted string is printed
(the old code also assumed that no option name contained a '%').

No functional change intended.

gcc/ChangeLog:
* diagnostic.c (diagnostic_report_diagnostic): Eliminate
save/restor of format_spec.  Move option-printing code to...
(print_option_information): ...this new function, and
reimplement by simply printing to the pretty_printer,
rather than appending to the format string.

diagnostic_report_diagnostic: refactor pragma-handling

* diagnostic.c (diagnostic_report_diagnostic): Split out pragma

RISC-V: Add -mstrict-align option

The RISC-V user ISA permits misaligned accesses, but they may trap
and be emulated.  That emulation software needs to be compiled assuming
strict alignment.

Even when strict alignment is not required, set SLOW_UNALIGNED_ACCESS
based upon -mtune to avoid a performance pitfall.

Float to int moves currently generate inefficient code due to
hacks used in the movsi and movdi patterns.  The 'r = w' variant
uses '*' which tells the register allocator to ignore it.
